Steering wheel wobble!

[D4N13L]

I have noticed when on the motorway and cross the cats eyes or a bump in the road the steering wheel gives a little shake and then stops. It does it on normal roads too above 50mph and there is a little bump in the road!

Does anyone have any idea what could cause it?

Could be a buckled wheel or one might not be balanced right. Could just be the road but i would check my wheels over.
